I’ve heard parents articulate reasons for college soccer this way, but they often leave out one reason I hear from some kids who really want D1 (although you have to dig down before they articulate it this way). They are used to — indeed crave — an intense practice/training schedule with similarly intense people. They hear that D3 is less intense - it’s off more (or completely) during the Spring except for player-initiated stuff, while D1 has some practices/scrimmages, mandatory fitness/strength work etc. Parents think that allows for more balance, but to these kids that sounds less serious — more of an extracurricular activity than a way of life. It’s like 2 days/week practices rather than 4 to the kids. Sure, the players might be good in both, but they like the structure of more. They are the ones who want it every day and have to be convinced to take a day off. They are the ones who are annoyed when the kids aren’t serious at practice. They think it’s better even if they don’t get to play, because it has that year-round structure and intensity. They’ve gotten this far not caring so much about lost social opportunities (or the team is the only socializing they want anyway) and have found they do better academically when they are busy.
Of course, some kids get to college and find the academics more overwhelming, the social opportunities more tempting, or the practice grind more than can bear without the payoff in playing games and they quit, transfer (sometimes to D3), etc. Others thrive in it. It’s why you have scout team players who stay involved all four years in lots of sports. Point is that for some kids, they need an intense experience more than they need playing time or stardom.
This doesn’t automatically mean D1, but the rules and the facilities certainly enable it more easily. If you know this is your kid, the focus can be on what schools regardless of division level offer this experience and attract like-minded players. There are D3s that operate this way, but you probably have to dig deeper to find them.
